Hvad kan du bygge med Shopify Functions?

You can build custom discounts, volume and tiered pricing, customer-specific pricing, shipping and payment method rules, cart validation, and cart transformations such as bundles. Functions run server-side during checkout and are controlled entirely by your own code.

Any plan can install public apps from the App Store that include functions. But only Shopify Plus lets you build and deploy your own custom functions and apps, which is the entire point if you have requirements no standard app covers.

Functions run under tight execution time and memory limits and are designed for fast, deterministic logic. They cannot make heavy synchronous calls to external APIs mid-checkout, and each function type has a defined input and output scope, so complex rules often require multiple functions working together.

On Shopify Basic, you are limited to the functions that come bundled with public apps. On Shopify Plus, you can develop and deploy custom functions that fit your exact business logic. This is one of the core reasons complex brands choose Plus.

Yes. Functions are Shopify's replacement for Shopify Scripts, built for the new checkout extensibility architecture. If you are still running Scripts, you should plan a migration to make sure your logic continues to work once checkout.liquid is deprecated.
